I am currently working towards a PhD in microbial genetics. Before that I spent a bit over a decade working as a programmer, with most of that time spent writing computer games. I have degrees in Mathematics (MMath), Life Sciences (BSc) and Molecular Genetics (MSc).

comment How many humans have been in my lineage? Is it almost the same for every human currently living?
@Joe: It's a model. Any model will be, by it's nature, limited. The limitations are discussed in the paper, as is there potential impacts on the resulting number.

comment How many humans have been in my lineage? Is it almost the same for every human currently living?
@Joe: It's not my claim. It's the number given in the primary literature source I linked to. Other estimates exist but even then they only push it back to around 8000 years ago, still a small period of time in comparison to the time since the human/chimp split.

Apparently I fail at cut-and-paste, corrected.

comment Collective name for the X- and Z-chromosomes
While your point about hetero/homo is valid, I think that it's likely to be a more readily understood and less confusing term than major/minor.

comment Collective name for the X- and Z-chromosomes
I'm not a fan of this usage since the mechanism of function varies so widely and the major/minor distinction implies something about the functional role of the two types.

comment Why is oxygen needed for the electron transfer phosphorylation?
@GreekFellows: It depends on the anaerobic process you're thinking about. In anaerobic respiration there is a terminal receptor and electron transfer; however the majority (I think) of anaerobic energy production is not respiration but rather the shortened process you are thinking of.

comment “Same” DNA vs genes
It is not a duplicate of the marked question; that question only considers genes vs. DNA - this question asks about the conflict between 50% of genes being shared with siblings and 99% of DNA with chimps.

comment “Same” DNA vs genes
Sorry, I should have specified: the bolded bit of the answer is completely and utterly wrong. In fact the sequence similarity between chimps and humans is higher for genes than for non-coding DNA as you should expect. The rest of the answer is fine.

comment “Same” DNA vs genes
The proportion of the genome that is coding has absolutely nothing to do with the answer to this question. The same conditions would hold for, say, yeast which has a much higher C-value.
